[Bug other/19525] New: [4.0 Regression] In-build-tree multilib testing broken

[ebotcazou at gcc dot gnu dot org]

The new flat layout of the multilibed libgcc_s shared library in the build tree
has broken in-tree multilib testing on IRIX and Solaris because there are now
multiple shared objects with the same soname in the same directory.

Richard Sandiford's analysis for IRIX and plausible kludge:
http://gcc.gnu.org/ml/gcc-patches/2005-01/msg00437.html

The same analysis holds for SPARC/Solaris with the 32-bit compiler:

lrwxrwxrwx       13 Jan 19 01:13 libgcc_s.so -> libgcc_s.so.1
-rwxrwxr-x   138743 Jan 19 01:13 libgcc_s.so.1
-rwxrwxr-x   138743 Jan 19 01:12 libgcc_s.so.1.backup
lrwxrwxrwx       13 Jan 19 01:13 libgcc_s_sparcv9.so -> libgcc_s_sparcv9.so.1
-rwxrwxr-x   196553 Jan 19 01:13 libgcc_s_sparcv9.so.1
-rwxrwxr-x   196553 Jan 19 01:12 libgcc_s_sparcv9.so.1.backup

and the 64-bit compiler:

lrwxrwxrwx       13 Jan 19 01:10 libgcc_s.so -> libgcc_s.so.1
-rwxrwxr-x   262624 Jan 19 01:10 libgcc_s.so.1
-rwxrwxr-x   262624 Jan 19 01:09 libgcc_s.so.1.backup
lrwxrwxrwx       21 Jan 19 01:10 libgcc_s_sparcv7.so -> libgcc_s_sparcv7.so.1
-rwxrwxr-x   191368 Jan 19 01:10 libgcc_s_sparcv7.so.1
-rwxrwxr-x   191368 Jan 19 01:10 libgcc_s_sparcv7.so.1.backup
